Editing New Features in EPrints 3.3 (section)

== Upgrade Notes ==
* '''Backup your database''' before installing this update. While upgrading has been tested you should always backup your repository before installing updates that change your database schema.
* This is a new branch release that will make significant changes to your repository's database and configuration. Upgrading repositories may require fixes to appearance and/or configuration to continue working correctly.
* Thumbnails are no longer double-linked - the thumbnail document itself contains relations to its parent but not vice-versa. This is to reduce the occurrence of corrupted thumbnail documents linkages.
* ''text''-type fields will now use the ''longtext'' MySQL type, which can accommodate a full UTF-8 65k entry.
* The magic ''_fulltext_'' field name is replaced by ''documents'' in ''eprint__rindex'' (as-in terms from the document sub-objects).
* The screens for user profiles and saved searches have been replaced by the generic datasets workflow screens.
* <code>/cgi/search/XX</code> no longer treats ''XX'' as a search definition but as a dataset id, instead use <code>/cgi/search/archive/XX</code> and add ''XX'' to the list of Internal-supported search types <code>$c->{plugins}{"Search::Internal"}{params}{search} = [qw( simple/* advanced/* xx/* )];</code>
* The default and secure templates are now language neutral and live below <code>/lib/templates/</code> - upgrading repositories should consider migrating their existing templates. Along with other improvements, the new templates include an ie6.css that may be necessary for IE 6 clients to work correctly.
* CSS-defined colours have been refactored and are now located in <code>/lib/static/style/auto/colors.css</code>. The general look-and-feel has been simplified.
* Antiword is no longer used for indexing so isn't required (although still used for the doc &rarr; pdf 'toy' converter)
* Document upload methods and handling have been completely reworked - custom upload methods will require re-implementing
* To search a numeric range "upto" you must use the new '..X' syntax instead of '-X', which is now treated as a negative number equality
* The SWORD/AtomPub endpoint is now http://myrepo.org/id/contents (the correct <link> is included in new templates)
